The Linux-Ecology-HOWTO discusses ways to make
computers less harmful to our environment and to
solve some ecological issues. It explains how to
use Linux to save power and consumables like paper
and ink. Since it does not require big hardware,
Linux may be used with old computers to make their
life cycle longer. Games may be used in
environmental education and software is available
to simulate ecological processes.

Gutenprint (formerly Gimp-Print) is a collection of printer drivers for Unix/Linux that currently supports over 1400 printers. It emphasizes quality and flexibility, offering a wide variety of options to meet most printing needs. It includes a CUPS driver, an IJS-based Ghostscript driver, Foomatic data, an enhanced Print plugin for The GIMP, and other printer maintenance utilities. It can be used equally well for fast printing of text or critical printing of high quality graphics and photographs.

GNU C library (glibc) is one of the most important components of GNU Hurd and most modern GNU/Linux distributions. It is used by almost all C programs and provides the most essential APIs, including the C standard library and other standard libraries.

GNU V.E.R.A. (Virtual Entity of Relevant Acronyms) is a free list of acronyms, all of which are used in the field of computing. V.E.R.A. is primarily meant to be used as an online reference, although some efforts have been taken to make its TeX output look acceptable. It contains approximately 8100 acronyms.

Header Browser helps you to create documentation from your C/C++ header files. It is similar to JavaDoc, Doc++, or KDoc, but it doesn't just create documentation pages; it allows you to really browse your APIs using a five columns view like NeXT's HeaderViewer.

The Infrared-HOWTO (formerly known as the
IR-HOWTO) is an introduction to Linux and infrared
devices and how to use the software provided by
the Linux/IrDA project. This package uses IrDA(TM)
compliant standards. Remote Control (RC) via
infrared is not the aim of the project, though
this topic is partly treated in the HOWTO.

The Intro to Bash Programming HOWTO is meant for newbies who wish to learn how to write shell scripts for bash, the GNU Boure-Again shell. It contains several samples. It is very early in its development, but it is hoped that some people might find it useful.
